SLASHER FOR WARP-YARNS.

SPECIFICATION forming part of Letters Patent No. 764,767, dated July 12, 1904.

Application filed April 12, 1904:. Serial No. 202,730. (No model.)

To all w/mnt it par/.7, concern,-

Be it known that I, ALoNzo E. RI'IOADES, a citizen of the United States, and a resident of Hopedale, in the county of l/Vorcester and State of Massachusetts, have invented an Improvement in Slashers for arp-Yarns, of which the following description, in connection with the accompanying drawings, is a specification, like characterson the drawings representing like parts.

This invention relates to slashers for warpyarns, and more particularly to the construction and arrangement of the comb; and it has for its object the production of means to more completely separate the warp than is now possible.

Before the sheet of warp is wound on the beam in a slasher it passes through a comb, the teeth or dents being usually about threesixteenths of an inch apart, and it is very desirable in order to reduce warp breakage and make a smoother and finer beam of yarn to separate the warp into still finer divisions. The comb just referred to must be made very stiff in order to withstand the strain and hold the warp in place, the teeth being coarse in order to secure the requisite strength and resistance, and this has prevented, so far as I am aware, the construction of a comb with the teeth near enough to accomplish the desired separation of the warp while possessing sufficient strength to stand up to its work.

In my present invention I interpose an additional comb between the regular coarse and stiff slasher-comb and the beam, the regular comb acting to initially separate and open out the warp and taking all the strain of holding the yarn in position. The second comb having to withstand very little strain can be made with its teeth as fine and as close together as is desired, its duty being to effect the final and requisite separation of the warp as it passes onto the beam.

I have provided simple and effective means for holding both combs in position, the construction being such that the second or fine comb may be moved out of the path of the sheet of warp while starting up the slasher.

Figure l is a side elevation of a slasher of well-known construction with one embodiment of my invention applied thereto. Fig. 2 is an enlarged perspective view of the primary and secondary combs and the means for retainingthem in place. verse sectional detail on the line 3 3, Fig. 2,

looking toward the right; and Fig. 4 is a top or plan view of one of the comb-supports.

In Fig. 1 the warp is led from beams Bat the left through the usual size-box S and around a heated drum I), the warps passing thence around guide-rolls g g to the lease-rods L and then to the beam B the sheet of warp being separated or spread, the apparatus so far described being of well-known construction and operating as usual, it being understood that the separation of the warp intermediate the leasing means and the beam has been heretofore effected by a strong and consequently coarse comb, (indicated at O, Fig. l.)

The construction of the comb p01 is not essential to my present invention, and in Fig. 2 I have shown a series of teeth or tines I, mounted in a box 2 and projecting upwardly therefrom, the teeth being locked in place and securely held by a plate 3, fastened to the box.

In my present invention I inter-pose a second and much finer comb O between the usual comb O and the beam B Fig. 1, the general construction of the comb being the same as that of comb O. The comb O, which is the usual slasher-comb and which I will refer to herein as the primarycomb, has to be made very stiff and strong in order to hold the warp in place, the teeth being made coarse, heavy, and quite a distance apartsay about threesixteenths of an inch. The coarse and heavy character of this comb is shownin Fig. 2.

It is very desirable to more thoroughly separate the sheet of warp than can be done by a coarse comb in order to make a smoother and finer beam of yarn, and this I effect by the interposition of a fine secondary comb O, as shown. This secondary comb has little warp strain to resist, as that is cared for by the primary comb, and consequently I am enabled to make the teeth of such secondary comb quite Fig. 3 is a transfine and close together, greatly increasing their number, practically as fine and as many as may be desired. The teeth of the secondary comb are indicated at 5, Fig. 2, the box 2 and lockingplate 3 being substantially as shown for the primary comb C.

I have provided novel and effective means for supporting the combs in operative position, such means permitting the turning down of the comb-teeth out of the path of the warp when desired.

The side bars A of the frame on which the beam B and combs are mounted have rigidly attached thereto comb-supports (shown as fiat brackets 6) extended inward from the side bars and secured thereto, as by screws 7, the supports being arranged in pairs opposite each other. Each bracket has an upturned lug 8 at one edge near its inner end, and on the opposite edge a lateral extension 9 is formed (see Figs. 2, 3, and I) substantially opposite the lug, as shown in Fig. I. A boss 10 on the under side of the support serves as a bearing.

for a stud or pin 11, on which is mounted an arm 12, adapted to swing in a plane parallel to the vertical face of the lug 8, said arm carrying at its free end a looking or clamping screw 13. Two of the supports are employed for each comb, as shown in Fig. 2, and the arms 12 are first swung down into dotted-line position, Fig. 2, and. the comb-box is placed on the two supports, the back of the box resting against the lugs 8. The arms are then swung up into full-line position, and the locking-screws 13 are set up tight against the front plate 3, thereby firmly looking or clamping the comb-box in operative position with the teeth of the comb upturned in the path of the warp.

If it is desired to move the teeth out of the warp, the screws 18 are loosened and the arms 12 swung down, so that the comb-box can be turned over upon the plate 3, the extensions 9 then supporting the box with the teeth in horizontal position and below the path of the warp. This is convenient when starting up the machine with a new warp.

My invention is not restricted to the particular construction of the combs nor to the precise supporting means therefor, as various changes or modifications may be made by those skilled in the art without departing from the spirit and scope of my invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a slasher, a beam, side bars at right angles to the axis thereof, comb-supports rigidly secured to the bars and extended inward therefrom in front of the beam, each support having an upturned lug at one edge and a swinging locking-arm at the opposite edge, to

receive between them the comb-box, a clamping-screw on the locking-arm, to clamp the comb-box against the lug, and a comb the box whereof is mounted on the supports in parallelism to the beam.

2. In a slasher, a beam on which the sheet of warp is wound, primary and secondary combs mounted in parallelism to each other and to the beam, the teeth of the secondary comb being liner than 'those of the primary comb, inturned supports upon which the ends of the combs are adapted to rest, and. means to detachably lock the combs in operative position upon their supports.

3. In a slasher, a beam on which the sheet of warp is wound, primary and secondary combs mounted in parallelism to each other and to the beam, the teeth of the secondary comb being finer than those of the primary comb, supports upon which the combs are mounted and on which the combs may be turned out of the path of the sheet of warp, and means to lock the combs on the supports in operative position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
